Estimate your jumbo payment & reserves
💡 Cash reserves lenders will likely want
Estimate only. Shows principal & interest, LTV, and estimated reserves. Excludes property taxes, homeowners insurance, and HOA dues. With 20%+ down there's no PMI; below 20%, many jumbo programs use no-PMI structures, so no MI line is shown. Not a quote or commitment to lend; your actual rate, reserves, and terms come from underwriting. Figures current as of 2026.
How the jumbo calculation works
Three numbers matter more on a jumbo loan than a conforming one:
- Loan-to-value (LTV) — your loan divided by the price. At 80% or below (20%+ down), there's no PMI, and pricing is best. Higher LTV means stricter terms.
- Principal & interest — the amortized payment on a large balance, where even a small rate difference moves real money.
- Reserves — the amount you must keep after closing. On jumbo, lenders want 6–12 months of payments in the bank. This is the number buyers overlook, so we show it up front.
What's not here: property taxes, homeowners insurance, and HOA dues — real monthly costs your loan officer will fold into a full estimate. For the thresholds behind these numbers, see Requirements; for pricing, Rates.
Jumbo calculator FAQs
Does it show required reserves?
Yes — it estimates the 6–12 months of payments lenders want after down and closing, the number buyers most overlook.
Does it include mortgage insurance?
No PMI at 20% down; below 20%, jumbo often uses no-PMI structures, so no MI line is shown.
Is the estimate exact?
No — it excludes taxes, insurance, and HOA, and your real rate comes from underwriting.
What down payment should I use?
20% is standard (no PMI); some programs allow 10% or less; 25%+ can earn the best pricing. Try a few.
